Energy Pyramids

True or False. In this energy pyramid, the consumers on each level only get about 10 percent of energy that the trophic level before it has stored.

• True
• False

A pyramid shape is used to show the amount of available energy at each trophic level because... 

• energy decreases as you go up the food chain, just like the pyramid shape gets smaller as you go up. 
• energy increases up the food chain just like the pyramid shape gets smaller as you go up. 
• energy amounts are the same at each trophic level

If only 10% of an organism's energy is available for the next trophic level, what happens with the other 90% of the energy?

• It is destroyed after it is used up.
• It is used for life processes or lost as body heat.
• It remains for the next trophic level IF the predator consumes ALL of the organism.
• It is lost completely as body heat.

What makes an energy pyramid different than a food web or chain?

• It shows energy flowing from the top of the chain and downward. 
• The tropic levels are the opposite
• It shows the amount of energy in each trophic level
• It shows specific predator/prey relationships

Why are producers found at the base of the pyramid?

• They create all of the energy and therefore have the most energy of all of the trophic levels
• There are more plants than animals. 
• They begin the flow of energy in an ecosystem.
• All of these answers are correct.

What is the sun's role in the energy pyramid?

• to produce chemical energy for the ecosystem.
• to provide radiant energy for producers to convert to chemical energy. 
• to start the energy flow of the ecosystem. 
• to provide mechanical energy for producers to convert to chemical energy.

The diagram represents a model of a food pyramid.  Which statement best describes what happens in this food pyramid?

• More organisms die at higher levels than at lower levels, resulting in less mass at higher levels.
• Energy is lost to the environment at each level, so less mass can be supported at each higher level.
• When organisms die at higher levels, their remains sink to lower levels, increasing the mass of lower levels.
• Organisms decay at each level, and thus less mass can be supported at higher levels
